Chilicon/Generac microinverter cabling is made up of two parts, a Modular Trunk Cable (MTC) and a Modular Branch Cable (MBC).
1. The 10AWG MTC spans the distance between modules and comes in 1.025M, 1.7M, and 2.15M lengths to accommodate different 60/72 cell and portrait/landscape configurations.2. The 18AWG MBC is one length, 0.65M, and connects each of the microinverters to the MTC.
A Chilicon/Generac microinverter branch circuit requires (1) MBC per microinverter and (#micros-1) MTC per branch circuit as shown in the example below.
